Genetic Variability Studies for Economically Important Traits in Sunflower (Helianthus Annuus L.) by Hafiz Saad Bin Mustafa in CIACR - Lupine Publishers
The research was conducted in the research area of Department of Plant
Breeding and Genetics (PB&G), University of Agriculture
Faisalabad (UAF), Pakistan during spring 2014. The triplicated research
trial was laid out following randomized complete block
design (RCBD). Fifteen lines of sunflower were studied for genetic
variability and association of economic traits with seed yield.
The data were recorded on quantitative traits i.e. days to 50% flowering
(DFF), plant height (PH), number of leaves per plant (NOL),
head diameter (HD), leaf area (LA), filled achene (FA), 100 achene
weight (100AW), oil contents (OC), achene yield per plant (AY/P)
and qualitative traits i.e. head angle at maturity (HA), achene
color(AC). The recorded data were subjected to analysis of variance,
correlation and path coefficient analysis. The accessions were highly
significant for all traits under study. The accessions A-2.2
showed good performance for most of studied traits. The accession B-3.1
also show better performance followed by A-4.3 and
A-7.10. Genotypic correlations are higher than phenotypic correlations.
100AW, NOL, LA and HD had positive and highly significant
genotypic correlations with AY/P. Genotypic correlation of AY/P was
significantly negative with PH, DFF and oil contents. LA, NOL,
100AWand OC showed direct positive effect on AY/P. DFF, PH, HD and FA
had negative direct effect on AY/P - Lupine Publishers.
